1 19-535; Rev 2; 2/9 Video Filter Amplifier with SmartSleep General Description The video filter amplifier with SmartSleep and Y/C mixer is ideal for portable media players (PMPs), portable DVD players, and set-top boxes (STBs). The inputs can be directly connected to the digital-to-analog converter () outputs. The dual reconstruction filters remove high-frequency signals above 6.75MHz. The Y/C-to-CVBS mixer creates a composite video signal from luma and chroma. The four amplifiers each have of gain. The outputs can be DC-coupled to a load of, which is equivalent to two video loads, or AC-coupled to a load of 15Ω. The SmartSleep circuitry intelligently reduces power consumption based on the presence of the input signal and the output loads. When the does not detect the presence of sync on luma, the supply current is reduced to less than 7µA. The device only enables a video amplifier when there is an active video input signal and an attached load. The video amplifier remains on while a load is connected. If the load is disconnected, the video amplifier is turned off. The operates from a 2.7V to 3.6V single supply and is offered in a small, 16-pin TQFN (3mm x 3mm) package. The device is specified over the -4 C to +125 C automotive temperature range.

10 Detailed Description In the Typical Application Circuit (Figure 1), the current s on a video encoder generate luma and chroma video signals. The filters those signals and then adds them together to create the composite video signal. The output amplifiers drive the video connectors through a back termination resistor. SmartSleep Feature The SmartSleep feature is activated when the SMARTSLEEP input is connected to logic high. The SmartSleep feature provides intelligent power management by selectively disabling the filters and output amplifiers based on the presence of a luma video signal or loads attached to the outputs. If the SmartSleep feature is not activated and the part is not in shutdown, the filters and output amplifiers completely turn on, regardless of whether there is a video signal at the input and whether there are loads connected at the outputs. SmartSleep only works with DC-coupled loads. Standby Mode In standby mode, the filters and output amplifiers are off and only the active video detect circuit is operational. Quiescent current consumption is approximately 7µA (Figure 2). The active video detect circuit checks if sync is present on the signal. If no sync is detected the device remains in standby mode. 7μA NO VIDEO SIGNAL V DD VIDEO ENCODER COUT CHROMA YOUT LUMA ACTIVE VIDEO DETECT CVBS1 SMARTSLEEP CONTROL LOGIC CVBSOUT2 CVBS2 GND Figure 2. Standby Mode Operation 1

11 Active-Detect Mode The active video detect circuit slices the signal at 4.7% of the power supply (155mV for a 3.3V supply). If the transitions occur at a rate of 14.3kHz or higher, then a video signal is present. When the detects a video signal with sync at the input, the control logic enters the active-detect mode and enables the load sense circuitry (Figure 3). The supply current is typically 17µA. If an output load is not connected to any amplifier, the remains in active-detect mode. Eight times per second, each load-sense circuit checks for a load by connecting an internal 15kΩ pullup resistor to the output for 1ms. If the output is pulled up, then no load is present. If the output stays low, a load is connected. Full-Operation Mode If a load is connected to an output, the corresponding filter and amplifier turn on and remain on until the output load is disconnected. In full-operation mode, SmartSleep intelligently reduces the supply current based on the input signal presence and output loading. Figures 4 and 5 show which portions of the turn on and which remain off with different load configurations. In Figure 4, both filters and the Y/C mixer turn on to generate the composite video signal for the amplifier connected to. In Figure 5, only the luma filter turns on, and the Y/C mixer stays off. When an amplifier is on, it continually checks if the load has been disconnected by detecting if the amplifier output is sourcing current during a horizontal line time. If no sourcing current is detected within one horizontal line time (approximately 64µs), the load has been disconnected and the amplifier returns to active-detect mode. If, at any time, the input video signal is removed, the returns to standby mode. If the SmartSleep feature is not activated and the part is not in shutdown, then the filters and amplifiers completely turn on, regardless of whether there is a video signal at the CVBSIN input and whether there are loads connected at the outputs.

14 Inputs The video inputs and should be directly connected to the output of the video current. DC-coupling ensures that the input signals are ground referenced such that the sync tip of the luma signal is within 5mV of ground and the blank level of the chroma signal is between.5v and.65v. Video Reconstruction Filter The filter passband is 6.75MHz, which makes the device suitable for the higher bandwidth video signals from a DVD chip. Broadcast video signals actually require less bandwidth because of channel limitations: NTSC signals have 4.2MHz bandwidth, and PAL signals have 5MHz bandwidth. Video signals from a DVD player are not channel limited; therefore, the bandwidth of DVD video signals can push right against the Nyquist limit of 6.75MHz. (Recommendation ITU-R BT.61-5 specifies 13.5MHz as the sampling rate for standard-definition video). Therefore, the maximum bandwidth of the signal is 6.75MHz. To ease the filtering requirements, most modern video systems oversample by two times, clocking the video current at 27MHz. Y/C Mixer The Y/C mixer adds the luma and chroma signals together to create a composite video signal. Since chroma is a phase modulated carrier at 3.58MHz for NTSC and 4.43MHz for PAL, the chroma signal is ACcoupled into the Y/C mixer so that the variation in blank level from one video source to another video source does not affect the DC bias of the composite video signal. The highpass corner frequency of the chroma ACcoupling circuit is 3kHz. Outputs The video output amplifiers can both source and sink load current, allowing output loads to be DC- or ACcoupled. The amplifier output stage needs about 3mV of headroom from either supply rail. The has an internal level shift circuit that positions the sync tip at approximately 3mV at the output. The blank level of the chroma output is positioned at approximately 1.3V if the blank level of the chroma input signal is.5v. The blank level of the chroma output is positioned at approximately 1.5V if the blank level of the chroma input signal is.6v. If the supply voltage is greater than 3.135V (5% below a 3.3V supply), each amplifier can drive two DC-coupled video loads to ground. If the supply is less than 3.135V, each amplifier can drive only one DC-coupled or AC-coupled video load. Shutdown When is low, the draws less than 1µA supply current. All the amplifier outputs become high impedance. The effective output resistance at the video outputs is 28kΩ, due to the internal feedback resistors to ground. Applications Information Reducing Power Consumption in the Video s and have high-impedance input buffers and can work with source resistances as high as 3Ω. To reduce power dissipation in the video s, the output resistor can be scaled up in value. The reference resistor that sets the reference current inside the video s must also be similarly scaled up. For instance, if the output resistor is 37.5Ω, the must source 26.7mA when the output is 1V. If the output resistor is increased to 3Ω, the only needs to source 3.33mA when the output is 1V. There is parasitic capacitance from the output to ground. That capacitance in parallel with the output resistor forms a pole that can potentially roll off the frequency response of the video signal. For example, 3Ω in parallel with 5pF creates a pole at 1.6MHz. To minimize this capacitance, reduce the area of the signal trace attached to the output as much as possible, and place the as close to the video outputs as possible. 14

15 AC-Coupling the Outputs The outputs can be AC-coupled since the output stage can source and sink current as shown in Figure 6. Coupling capacitors should be 22µF or greater to keep the highpass filter formed by the 15Ω equivalent resistance of the video transmission line to a corner frequency of 4.8Hz or below. The frame rate of PAL systems is 25Hz, and the frame rate of NTSC systems is 3Hz. The corner frequency should be well below the frame rate. Smartsleep only works with DC-coupled loads. Power-Supply Bypassing and Ground The operates from a single-supply voltage down to 2.7V, allowing for low-power operation. Bypass V DD to GND with a.1µf capacitor.
